Considering he is approaching the end of his second term, it might be a bit late for President Obama to change American policy in substantial terms. But better late than never — it is critically important to learn from past failures.

Here follow some brief suggestions for him to digest:

1. North Korea's nuclear proliferation violated its treaty commitment and United Nations Security Council resolutions, and this issue will negatively affect this region. There is no doubt about that, but there is no consensus over how serious that challenge might be, and what might be the long-term repercussions if denuclearization is not achievable. It is time to rebuild consensus in this regard.

2. The United States has been working so hard using political isolation, diplomatic pressure, economic sanctions and military deterrence against North Korea, however, that did not work well. Might it be the time to try an alternative approach? The Obama administration also needs to think harder about whether its military deployment and other moves are conducive to promote cooperation and coordination among major powers on this issue.

3. The Obama administration has been very much frustrated by North Korea, and truly believes negotiation would not work. Nothing positive comes out of this posture, while negative outcomes are accumulating gradually. The Obama administration's policy is neither soft enough nor tough enough. Then, why not approach North Korea diplomatically?

4. Neither China nor the United States is ready to accept the deteriorating situation, and both countries share common goals but differ in approaches. Might it be the time for both countries to meet halfway, to work together addressing this issue instead of finger-pointing at each other?

Certainly President Obama can go ahead with his "Strategic Patience" strategy, but it is a doomed-to-fail strategy. His foreign policy legacy will be judged not only by his success in rapprochement with Myanmar and Cuba, the nuclear deal with Iran, and the withdrawal from war on terror, but also by his policy toward North Korea.
